Regarding the formation of the oceans, the Book of Genesis mentions the following:

Quote:1 In the beginning God created the heavens and the earth.
2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.

[...]

6 And God said, “Let there be a vault between the waters to separate water from water.”
7 So God made the vault and separated the water under the vault from the water above it. And it was so.
8 God called the vault “sky.” And there was evening, and there was morning—the second day.

9 And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so.
10 God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good.

Since there is not enough water on earth (oceans + glaciers + underground aquifers) to flood the entire planet, some creationists claim the water came from outside the earth. This water is supposed to be that separated from the oceans. Old drawings illustrate it like this:

This idea is incredibly silly because the supposed water above the sky has never been observed during the numerous times that we have left Earth’s atmosphere to explore space. However, the European Space Agency (ESA) recently discovered a gas cloud, Lynds 1544, located in the constellation of Taurus that is laden with enough water to fill 2,000 earths. Astrophysicists originally thought water located in such areas was frozen into dust, but the ESA believes cosmic radiation keeps it in vapor form. The water in the cloud is collapsing towards the center, which might lead to the formation of a star. (Whether this occurs in all sun-producing gas clouds is unknown to me.) You know the creationists are going to be cherry-picking this bit of science to claim this is where the flood waters came from. It’s inevitable. I give this a few days before it starts appearing on their blogs and in their “scientific” articles.

This of course does not prove their claims because, as I previously mentioned, there is no large reservoir of water vapor located directly outside of the earth, and if water vapor was located in the gas cloud that formed our sun, it dissipated long before the formation of the earth. Most importantly, there is no evidence for a world flood ever taking place.

I was taught this theory as a kid. But I never heard that there was supposed to still remain a space reservoir. I was taught that all that orbiting water was used for the flood so that's why you don't observe it today.

It was also the reason why people lived so many centuries old in the ante-diluvian world. The vapor in the upper atmosphere kept harmful ultraviolet rays from aging the human population.

It's not "silly" unless you expect ancient Near Eastern people with no science to know anything about the structure of the universe. The graphic is more complete than most, but is missing the "pillars", and a few other things.
It's only "silly" to "literalists", (which is understandable, since that's the atmosphere we operate these days), in *some*, and only *some* parts of religion.
The best graphic I've seen of ancient Sumerian cosmology is in the intro to the New American Bible, (the Catholic version). No one, (except the nut cases, and there are plenty, I suppose), actually takes it literally. Aren't you an art guy ? Come on. I know you're no literalist.

Shows what these scientists know.
When pressure on a liquid is reduced, so is that liquids boiling point.
Space has a pressure of zero and so hence the water will vaporize.
No radiation needed.

You can do basic experiments with a soft drink bottle and a bit of liquid. By using a pump to suck out the air you can change the pressure of the inside of the bottle and turn the liquid in a bit of a 'poof' into vapor.
It's also seen when taking a lid off a fizzy bottle for the first time, when you get that 'poof' and there's like a cloudly mist, that's because of a change in pressure.
